The life of a carbon filter is difficult to predict because background VOC levels vary from house to house.
Therefore, we recommend doing what is called a "smell test" to know when to replace the carbon filter. Here's how to do a smell test: Open the purifier and remove the carbon filter - hold the middle of the carbon filter to your nose (within 1-3 cm) and smell the carbon filter. If you smell a sour, acidic or chemical odor, your carbon filter is saturated and should be replaced.
Typically, carbon filters should be replaced every 12 months, but this can fluctuate depending on odor concentration. For larger forced extraction systems, standard designs will require media replacement once a year, but this can be extended to 24 months at customer request.
Replacing the carbon filter will ensure that the filter is functioning properly to remove contaminants such as odorous compounds and gases, organic chemicals and sulfur compounds such as H2S and volatile organic compounds (VOCs).
Activated carbon filters reduce odor emissions by up to 99.5%. Industrial carbon filters are an essential component in the process of removing harmful and odorous compounds from polluted air streams.
These important devices help protect employees who work near these gases while minimizing complaints from surrounding businesses and residents near the facility. They are most commonly used to remove pollutants such as volatile organic compounds (VOCs), sulfur compounds, and other odorous gases.
